24-Core Liquid Cooled Desktop

The Adamant Custom system is a new gaming desktop PC built around a 24-core Intel Core Ultra 9 285K processor and an Nvidia GeForce RTX 5090 graphics card with 32GB of video memory. It ships with 32GB of DDR5 memory and a 1TB NVMe SSD, running Windows 11 Pro from a tower chassis cooled by a 360mm liquid cooler.

Suited for high-end gaming and creative work

This configuration targets users who need maximum single-thread speed and GPU compute for 4K gaming, rendering or AI workloads. The four memory slots allow expansion up to 192GB for larger datasets. Buyers who want more storage than the single 1TB drive provides, or who need additional drive bays beyond the one 3.5-inch or two 2.5-inch bays, should look at a different platform.

Sustained load behaviour

A 1200W 80 PLUS Gold power supply feeds the CPU and GPU while the 360mm quiet-edition liquid cooler and four 140mm case fans running at 1500rpm maintain thermal headroom during extended sessions. The motherboard includes Thunderbolt 4, USB 20Gbps and 10Gbps ports plus 2.5Gbps Ethernet and Wi-Fi 7 for high-throughput peripherals and network traffic without throttling.

Questions about this item

Does the Ceres 300 case include a USB Type-C port on the front panel for my existing peripherals?

The front I/O provides one USB 3.2 Gen 2 Type-C port plus two USB 3.0 Type-A ports and an HD audio jack.

Will the 2.5Gbps LAN port work with my current Gigabit switch and cabling?

The integrated Intel 2.5Gb Ethernet controller auto-negotiates link speed and is fully compatible with Cat5e or Cat6 cables and Gigabit switches.

How can I verify the 360 mm liquid cooler is keeping the 24-core CPU within safe temperatures after assembly?

Monitor the CPU package temperature in Windows Task Manager or HWMonitor while idling and under load; the cooler is rated for the Ultra 9 285K thermal design power.
